Application inea June 3,1899; sesam. 719,794. nro model.)

To all whom t may concern.-

Beit known that LWILLIAM T.-HANAWAY, a citizen of the United States, residing at Seymour, in the county of Baylor and State of Texas, have invented new and useful Improvements in Machines for Generating Noxious Fumes and Utilizing the Same for the Destruction of Animal Life, of which the following is a specication.

The object of my invent-ion is to provide a machine for generating noxious fumes or gases and forcing or conveying the same to a distant point for the destruction of animal life.

The invention is particularly designed for use as an exterminator for prairie-dogs,means being provided whereby the fumes of sulfur may be discharged into the dog-holes, which suocate the dogs and cause their instant death.

Specifically stated, the invention consists of a fire-box or heater, a roasting-chamber or generator above the heater, a suction-fan, a conduit leading from the generator to said fan, a pipe or conduit leading from said fan through said generator and discharging into.

the dog-hole, a hopper for sulfur leading into the. generator, feed mechanism therefor, a

drive-shaft, gearing between said drive-shaft and said fan, and feeding mechanism whereby upon the actuation of the former the latter will be operated.

The invention also consists in certain details of construction and combinations of parts, whichwill be hereinafter more fully described and claimed.

In the drawing forming part of this specification .the figure thereof represents a sectional side elevation of a device constructed the fire-box or heater 3 and communicating with the roasting-chamber or generator 4 is an auxiliary suction-pipe 6, for a purpose which will presently appear. At the rear end of the frame 1 is mounted afan 7, commud nicating with the casing of which and leading from the generator 4 is a suction pipe or conduit 8. Leading from the fan-casing and extending through the generator 4 is a forcepipe v9, which has a flexible connection 10 between it and the nozzle 11, which is intended to be inserted into the prairie-dog hole. Also mounted in the frame above the fire-box and generator is a hopper 124 for the supply of sulfur to the `generator 4, said hopper com municating withl said generator through a chute 13. Feeding mechanism, consisting of a cut-off slide 14,is provided between the hopper 12 and the chute 13, the same being actuated through a pitman 15, pivoted to a crank arm 16 on the shaft to which the sprocket-wheel 17 is secured.

The operating mechanism for the .machinel consists of thedriveshaft 18, having acrank 19 thereon, by means of which it can be turned, a sprocket-wheel 20, secured to said shaft and gearing with a sprocket-wheel 21 on the counter-shaft 22 through the chain 23. The shaft 1S is further provided with a sprocket-wheel 24, which is geared with the sprocket-wheel 17 through the chain 25. In addition to the sprocket-wheel 21 the counter-shaft 22 carries a sprocket-wheel 26, which is geared through the sprocket-chain 27 with a sprocket-wheel 2S on theshaft of the fan 7.

Constructed as above described the operation is as follows: It will be understood, of course, that thefireis lighted in the fire-box 3, and that a supply of sulfur has been fed into the generator 4, and that thevalve 5 isl open for the admission of air to said generator. By turning the shaft 1S through the crank 19 the feeding mechanism for the hopper 12 and the fan 7 is thrown vinto operation. This causes an intermittent butcontinuous feed of sulfur from said hopper 12 to the generator 4 and a suction through the conduit 8 from the generator 4 into the fancasing. This drawsoif the fumes of sulfur which have been generated,'and the same are forced by the fan through the conduit 9, dexible coupling 10, and nozzle 11 into the prairiedog hole or other place where said fumes are to be used. By means of the auxiliary or supplemental suction-pipe 6 a forced draft is given to the fuel in the fire-box 13 and the IOO products of combustion are led into the generator et and drawn off With the sulfur fumes and utilized for the destruction of animal life. f

Having thus described my invention, what I desire to secure by Letters Patent isl,

I. In an apparatus for generating noxious fumes or gases and utilizing the same for the destruction of life, the combination with a rire-box or heater, of a generator, a fan, a conduit leading from said generator to said fan, a conduit leading from said fan for the discharge'of the fu mes or gases, and an auxiliary suction-pipe leading from the fire-box to the generator.

' 2. In an apparatus for generating noxious fumes or gases and utilizing the same for the destruction of life, the combination with a fire-box or heater, of a generator, a fan, a conduit leading from said generator to said fan, and a conduit leading from said fan for discharging the f urnes or gases, the same passing through saidV generator.

3. In an apparatus for generating noxious fumes or gases and for utilizing the same for the destruction of life, the combination with a nre-box or heater, of a generator, a fan for drawing off the fumes or gases from said generator and for discharging the same at the iary suction-pipe leading from said firefbozly .to said generator, a fan, a conduit leading from said generator to said fan for drawing oft the fumes or gases, and a conduit leading from said fan and passing through said gen y, y 45 means for supplying sulfur or other material from whichvthe'fumes are made to said 'genf eratorV for discharging the fumes or gases, and

erator.l

In testimony whereof I have hereunto Set' Y.: l Y
